"The CCA trio and the Vader Balanced are similarly tuned, but both are one of the best iems under 30 usd."
"I downgraded from the meet 2 to se since I was only using 1080p and am happy with my choice! ... If you’re planning on just doing 1080p I’d save the cash and go meet se."
"JLab go sport + FTW. ... I have the same sweaty ear issue and the beats fall out of my head. ... The jlab are cheap and even they stay in. (Because they hook over your ear)"

"Shit man, I still got them and they still work great. Oldest one close to 15 years."
"I use a 30 year old Coleman 6 person. I probably average 20 nights a year with it."
"I spent $80 on a six person and it went through multiple rainstorms a year. It started leaking after 6 years. Up until then, it kept us dry as a bone."

"The first month the filter got nasty so I replaced it. Now the filter has been staying fairly clean for 3 months, there is no dust on my ceiling fans, and the vacuum is picking up a lot less. This is in a house with 2 cats."
"I have quite a few allergies, and when we adopted a dog, they became quite serious to the point I needed puffers and was rediagnosed with asthma after 20 years of no issues. I bought a Germ Guardian for the bedroom and I ran it 24/7. It was a lifesaver."
"I lived in city during first part of my pregnancy and the smells and air quality were stifling to me, so I bought one and it was a huge improvement as I could actually tolerate the air in my apartment without feeling sick."

"the medify one sounds horrible- it has a weird high pitch and i can’t stand it even on the very lowest setting. ... i actually sent it back and they replaced it and the second one sounds the same."
"The Germ Guardian air purifiers from Costco are incredibly noisy and create a constant high-pitched noise at *any* setting."
"Levoit Core 300 was decent on specs, but it hummed just enough to wake the youngest every other night."

"The unit I bought said around 1300 continuous watts. Bullshit. This thing regularly pulls 1800 for lengths of time."
"expensive to run (electric bill)"

"I literally just bought the Airmega 350 on Amazon and immediately regretted since I can't find the replacement filters for sale anywhere. ... Coway finally responded but wasn't helpful. They said they don't know when the filters for the 350 will be released."
"450 is round. New design. Not as good but more trendy. ... Higher claimed CADR. It is round so that number will go down rapidly. ... The VERY SHORT version, although ... there's a sticky ... is that round units are not inferior due to their shape. They're inferior because ALMOST WITHOUT EXCEPTION they have: * No removable pre-filter * Minimal Carbon, placed after the main filter * Deformable main filter * Smaller fans which have to spin faster to move more air therefore have a shorter lifespan * Shorter filter life leading to more costly replacement * Questionable filter efficiency, since it's difficult to manufacture a deformable HEPA filter. Levoit in particular claimed their filters were HEPA but they weren't at the time. They might be now, since they've started shipping them reinforced. * Instructions to VACUUM YOUR FILTERS, which pretty much means they're not HEPA. ... The airmega round units are, unfortunately, no exception."
"filter replacements can get pricey though ... filters are WAY overpriced considering you can get the machine with 2 filters for $120.."

"I have that issue with a germ guardian right now. I tore it apart and the bearing is designed to be inaccessible."
They don't really work if you have an active infestation. Ive got 4 lg ones in an 800sq ft house and I swear they do almost nothing. We even have this electrostatic filter in the hvac and still I've get systems when the doors close or the AC goes on. I have 2x airmega 200s, germ guardian rated for 900 sq ft, coway with uv rated for 600 sq ft. 2 upstairs and one down. If I were you id try to build the biggest Rosenthal filter or several as they don't get down hall ways or around stairs, etc. The think I don't like is they really tank your electric bill and are very noisy, as they have to stay on high mode.
r/ToxicMoldExposure • Air purifiers you swear by? ->Blues air or GermGuardian with UV. I’ve had mine for years and it’s been great
r/homeoffice • Best air purifier ->I used this national allergy website. I got the Dyson and the germ guardian. Honestly I don't think the Dyson is worth the money. https://www.natlallergy.com/
r/Allergies • Best Air Purifier and Vacuum for Seasonal Allergies and Pet Dander ->I have used ALEN and GermGuardian HEPA, I got the GG first and ALEN as a second one later. They definitely do something, I lived in city during first part of my pregnancy and the smells and air quality were stifling to me, so I bought one and it was a huge improvement as I could actually tolerate the air in my apartment without feeling sick. They filter noxious smells pretty well, I used to live with people who smoked 🍃and I was able to keep the smell out of my room with it, so it definitely did something. I always see Austin air and air doctor recommended, and some specifically for issues like mold. Idk if it’s hype, like someone said you could get a box fan and air filter and make your own. But, Air Doctor is doing a presale on their new model at half price so it’s around $400 instead of $800, but doesn’t come out until summer. I just bought it as i need one for other room and thought id see if it makes a significant difference compared to the ones i have.
r/moderatelygranolamoms • What is the best air purifier brand for home you prefer over the others on the market? ->Coway, GermGarurdian, and Blueair are all top rated. I personally have 2 blueair they work great I have 2 cats and my thanksgiving guests couldn’t smell them or their litterbox at all!
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->Germ guardian!! Have had one for about 10 years and the newest one about 7 years....they are work horses!
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->I like my WINIX for these larger particles. It has a cleanable pre filter, charcoal filter and the hepa. I vacuum the pre filter weekly to get the cat fur off. I also use an old germ guardian that was my best buddy in a musty old office I worked. It’s still a great unit just louder like a fan so I use it in the bedroom as white noise now It’s worth mentioning a reminder to change the home furnace filter if you have one. I tend to change mine every 1-3 months during high allergen or fire seasons.
r/AirQuality • BEST AIR PURIFIER FOR THOSE STRUGGLING WITH ALLERGIES ->I have quite a few allergies, and when we adopted a dog, they became quite serious to the point I needed puffers and was rediagnosed with asthma after 20 years of no issues. I bought a Germ Guardian for the bedroom and I ran it 24/7. It was a lifesaver. I bought one for the main floor and one for the basement and they have really helped. I highly recommend getting one, at the very least for your sleeping area.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->Yes! I got one at first and now we have 3! They work so well. Gets rid of weird smells, room not so stale, air noticeably cleaner. I got germ guardian but the others are different brands my Costco had. For filters, I buy the knock off brand ones that fit in my machines and they work fine but significantly cheaper than brand name filters
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->I bought a couple of Germ Guardian purifiers off of Amazon after Woolsey and they’ve performed well.
r/AskLosAngeles • Air purifier suggestions!? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
